To all whom vit ma amare:

Be it known their we,

Hnuur P. Bnvnnn, both citizens of the United States, residing in the 'town of In.-

dependence, county of Montgomery,' and State ot Kanso s, have invented certain new u and. useful Improvements in A peratus for Treating Oil, of which the foiiowng is a. specticetion. f

r This invention relates to an apparntus .for

treating coil, and refers more particularly tomi apparatus which is adapted for' the crock'ing of 1petroleum oil to produce from the relative y heavy constituents thereof lighter or lower hoiliug pontconstituents.

The object of the' invention is 'to provide a v Construction in which the heating chamber permits of e, bullet-like 'velocity of the oil in its pasen e through the heating chamber or coil vfhi e at the same time obtaining a maximum heating area from the same lengths of tubes, as for example, more than :four times' the'heating area of plain tubes. This Will grestly cut down the Construction 255 cost 5* the tubes :tre spirally corrugated tubes as shown more clearly in the drawings:

In the drawings: Fig. 1 is a view, partly in side elevation and partly in vertical section, of our im- 3o proved spperatus,

- Fig. 2 is an enlarged sectional detail View of one of the spirally corrugted heating elements. v

-Refcrring in detail to the drawings, 1 designates the furnace provided With grate 2, bridge -wall 3, burner 4 and stack 5. In the urnace is mounted the heating element which is one of the novel features of the Construction and consists of a coil or a plu- 'alitv of coils or pipes 6, each of which takes' the form of a. spirally corrugated tube 7 as shown more clearly in. Fg. 2. The inlet side or the coil is connected to feed line 8, having a valve 9 and leading to charging pump 10. The inlet side of the pump s `ro'nneeted by pipe 11 having valve 12 to any suitable source of raw oil supply. The outlet side of the heating coil is connected by transfer line 13 to a vapor or expans'on 59 'chamber 14.' This expansion chanber lil is provided with vapor outlet 15 having GUSTAV Eotorr and' throug throttle valve 16 and extending into the lower end of a dephleg'mator 17. The upper end of the pipe 15 is provided with a spaoed cup member 18, to ermit the vupors to pass out of the pi e 15 "into the condenser or dephlegmator wnile reventing the refiux condensate from fu ling back into the pipo 15. Betim; condensate pessesout ot' the clephle mator back to the heating coil h pipe 19 regulated by throttle valve 20. The upper partot the dephlegmator is connected by the vapor line 21 having a throttle valve 22 to condenser coil 23 seated ,in condenser box 24:. The lower end of the coil 23 is connected by pipe 25 having throttle valve 26 to the upper end of receiver 27. This receiver 27 has the usual liquid level gauge 28, pressure gauge'29 and liquid and gas outlets 30 and 31, controlled by valves 32 and 33 respectively.

From the forcgoing it Will be seen that the oil to be treated can be continuously fed to the heating zone and eaused to have a spirally revolving motion as it passes through the heating coil. The arrangement is such as to give a maximum heating area as reterred'to and at the same time permit i of the raw oil being ted at high vclocitv through the heating chamber or other heating element. I

In carying out a process to crack oil with this apparatus, gas oil, for example, may be heated to a temperature of 750 degs. F. in the coil and subjected to a uniforn pressure of pounds throughout the system or differential pressures may be obtained by regu lating the valves shown. I

We claim as our invention:

In an apparatus for cracking hydrocarbon oil, the combination with a turnace of a coil the -ein for the passage of oil, said coil consisting of a plurality ot' spirally corrugated tubes passing through the furnace and through which the oil must pass, a vapor chamber in communication with said tubes, a dephlegmator communicating with said vapor chamber, and a condenser communicating'wth said dephlegmator.
